March 31 was something of a... busy day on the calendar, so some people may not have noticed that it was also World Backup Day. It's as good a day as any to remind people about how important it is to back up your data. People today are generating more and more data. As our infographic shows, the mobile devices that are part of many of our lives generate - and store - amounts of data that would have been unthinkable not too long ago. Add to that what we generate elsewhere and people have significant amounts of digital "stuff". Important data needs to be backed up, because losing them could cause all sorts of damage: from the emotional (say, lost family pictures) to the financial (business records). How can you do it? The accepted rule for backup best practices is the three-two-one rule. It can be summarized as: if you're backing something up, you should have:
- At least three copies,
- In two different formats,
- with one of those copies off-site.
